hi trying to fix eml light, diagnostics coming up p0130, bank 1 sensor 1 circuit malfunction, and p0443 evap valve circuit malfunction, steps ive taken to fix inc, new o2 sensor precat, new evap valve, but still after clearing both dtcs they return, checked carbon canister, fitted new filler cap. 12v going to evap valve and if i manualy earth it it clicks, im hoping its not ecu problem, checked earth on ecu and thats ok. only option left is check signal wire to evap valve but i dont have a ecu pinout, im going to try and find signal wire at ecu plug and connect a wire direct to valve and see if theres a break in the loom, must add ive changed maf aswell and tried the yellow wire from maf and its earthing ok, any sugestions would be great, thanks.
